We explore the gravitational instability of clumpy and turbulent gas discs, taking into account the Larson-type scaling laws observed in giant molecular clouds (GMCs) and H i, as well as more general scaling relations. This degree of freedom is of special interest in view of the coming high-z interstellar medium surveys and is thus potentially important for understanding the dynamical effects of t
INTRODUCTION: Beta-cell replacement by human islets or whole pancreas offers a life-saving therapeutic remedy for patients suffering from type 1 diabetes, providing considerable advantages with respect to diminishing total daily insulin dose and lowering frequencies of debilitating hypoglycemic reactions as well as preventing chronic micro- and macrovascular complications. Although remarkable prog
The aim with this paper is to examine how different GIS-based visualization methods can be applied and come to practical uses in the emergency service’s fire preventive work. These techniques motivate and facilitate various forms of fire prevention such as selection of areas or neighborhoods, blocks or buildings before home visits, identification and targeting of different risk groups and customiz
Emulsification is a common process in the production in many non-solid foods. These food-emulsions often have high disperse phase volume fractions and slow emulsifier dynamics, giving rise to substantial coalescence during emulsification. Optimal design and operation of food-emulsification requires experimental methods to study how emulsification in general and coalescence in particular progresses
The aim is to illustrate how web marketing frame commercial baby food as a value-adding part of weaning practice and discuss how various ways of framing relate to contemporary mothering ideals. Drawing on “practice” and “frame analysis,” we illustrate how four baby food producers’ web marketing frame commercial baby food and weaning as “medical,” “fun” or “convenient.” The analysis shows that the
Analysing and understanding energy consumption from the household activity perspective is vital for developing policy that promotes sustainable everyday life. Doing so entails learning how to connect policy with household activities and everyday life. We use a time-geographic visualization to analyse several dimensions of everyday life as a totality. From household members' time diaries, we can an
In order to improve curve safety, warning signs are used to alert drivers to unexpected changes in horizontal alignment and speed variations. While all countries have standards and guidelines for signs, markings and delineations to ensure a uniform system, they do not use them in the same way and choices and combinations may differ. SAFESTAR project promoted a method for establishing uniform curve
In this paper, we consider a mobile platform with two cameras directed towards the floor. In earlier work, this specific problem geometry has been considered under the assumption that the cameras have been mounted at the same height. This paper extends the previous work by removing the height constraint, as it is hard to realize in real-life applications. We develop a method based on an equivalent
Car-sharing systems with electric vehicles are an alternative to reduce commuting times in big cities and also to mitigate air pollution. Car-sharing exists in 1100 cities around the world. These systems have had positive effects in the cities, replacing between 9 and 23 private vehicles for each car. This document proposes a public car-sharing system for Bogotá. The article focuses on the design
This review summarizes – with the practicing hematologist in mind – the methods used to determine measurable residual disease (MRD) in everyday practice with some future perspectives, and the current knowledge about the prognostic impact of MRD on outcome in acute myeloid leukemia (AML), excluding acute promyelocytic leukemia. Possible implications for choice of MRD method, timing of MRD monitorin
Solid-state synthesis in the Bi-Se system produced both commensurate and incommensurate phases of compositions ranging from Bi2Se3 to Bi4Se3, all crystallising in rhombohedral or trigonal layer structures. The a parameters are very similar for all phases but the c parameters vary irregularly between 10 and 100 Å. A general model for all these phases was developed, using single crystal X-ray diffra

Throughout time, communities have adapted to changes in their environment and, in doing so, have addressed risksthat threaten the things they value. The need to adapt is considered more urgent now than ever, notably given thecurrent focus on climate risk. Typically, adaptation is presented as a solution to reduce such risks. This is particularlythe case for Landlocked Developing Countries and Smal
X-ray imaging using a Talbot-Lau interferometer, consisting of three binary gratings, is a well-established approach to acquire x-ray phase-contrast and dark-field images with a polychromatic source. However, challenges in the production of high aspect ratio gratings limit the construction of a compact setup for high x-ray energies. In this study we consider the use of phase gratings with triangul
Botulinum neurotoxin B is a Food and Drug Administration-approved therapeutic toxin. However, it has lower binding affinity toward the human version of its major receptor, synaptotagmin II (h-Syt II), compared to mouse Syt II, because of a residue difference. Increasing the binding affinity to h-Syt II may improve botulinum neurotoxin B's therapeutic efficacy and reduce adverse effects. Here we ut
The predictions of chiral perturbation theory for the weak non-leptonic decays of hyperons are examined beyond the leading order. For the S-wave amplitudes we find that the leading corrections to lowest order chiral perturbation theory preserve the vanishing of the Σ+ → nπ+ amplitude. However, the Lee-Sugawara relation gets a large correction indicating a breakdown of chiral perturbation theory fo
